Floor deck is the plate which supports the floor concrete that is called the pressed steel plate, also called the floor bearing plate and the steel bearing plate. It has three types: Open floor deck-necked floor deck-closed floor deck.
In short,Roof decking floor profiles are typically used as the structural component. The steel decking floor is a cold-formed steel sheet. Metal Decking use in roof and floor systems for supporting the concrete or insulating membrane of a roof. Its design and construction magnify properties of the steel. It causes to create a high strength-to-weight ratio that lowers the material, handling, and erection costs.In addition to, Steel Floor decking roll forming machine
This is the new type we engineer for decking machine, used for building surface panel. Metal Deck Roll Forming Machine is a modern, pre-eminent solution for concrete floor work.We can design metal deck roll forming machine according to your drawing profile.
Necked floor deck–Steel Deck Roll Forming Machine, some place is also called ie as versa-Dek metal decking Machine. Versa-Dek metal decking is ideal for use in mid-rise residential structures. Dovetail system provides the thinnest total floor depth, reducing story height while maximizing ceiling height, with clear spans up to 28 ft. Versa-Floor is non-combustible and is fire-resistance rated up to four hours without protective coverings such as gypsum and spray-on materials.
Features of this type metal decking:
Also call it as dovetail profiled steel plate production line which is a new generation product recently launched by our company. This unique form of metal profiled plate is beautiful in appearance, easy to install, and has good mechanical properties and fire protection. Performance, suitable for any floor. For these two types of floor deck hanging accessories, the bottom of the floor deck is almost flat, and the narrow inverted dovetail mouth is very convenient for hanging. Such as suspended ceilings, water and electricity pipes and other equipment, without pre-burying, drilling, electric welding, etc., play a key role in the damage during construction and the integrity of the concrete.
Experiments have proved that it has stronger bearing capacity and shear resistance than other open floor deck systems. The special design of the closed rib shape allows the slab ribs of the steel bearing slab to be completely surrounded by concrete, just like the steel bars in the cast-in-situ slab, so as to maximize the respective characteristics of steel-concrete and successfully applied to the reinforced building. In the bearing system, it has excellent fire resistance.
It is a kind of lightweight and high-strength profiled steel sheet formed by rolling and forming of 1250mm wide high-quality cold-rolled hot-dip galvanized steel sheet. It adopts a dovetail necking design with an effective width of 768mm and a wave height of 16mm.
Compared with OSB board, its material property is steel plate, which is not corroded by termites. In southern areas where termites are frequent, it can effectively replace OSB board for external walls.
Compared with other flat plates, the concave-convex groove structure can effectively engage with the cement mortar leveling layer, which greatly enhances its overall stability and prevents delamination.
3.Effectively prevent thermal expansion and swelling
The expansion coefficient is 1.2×10°/℃, which is slightly affected by temperature changes; its material is steel, which does not shrink and expand with moisture content, which can effectively control its deformation without stressing the light steel structure itself, nor due to Large deformation causes cracking of the leveling layer or surface layer.
